Patent CA-2292753-A1 (CA)
Inventor: AUBRY JEAN-CLAUDE
IPC: D01F6/82
Filed: 1998-06-05
Abstract: The invention concerns a thermotropic aromatic polyester(amide) as-spun monofilament, verifying the following relationships: D ? 40; Te > 45; .DELTA.L ? 0, D being its diameter (in µm), Te its toughness (in cN/tex), and .DELTA.L being its variation in length (in %) after 2 minutes at 235 ± 5 ·C under prestress of 0.2 cN/tex. The invention also concerns the spinning method for obtaining such a monofilament, consisting in particular, at the die outlet, in structuring the polymer flow by drawing it in a gas fluid layer for a predetermined duration which is a function of the diameter D, before the resulting structured polymer flow is hot-dipped in a liquid for its solidification.

Title: Enhanced flexibility surgical stent
Inventor: FRANTZEN JOHN J
IPC: A61F2/06
Filed: 1998-06-12
Abstract: A surgical stent (10) is provided which can be radially expanded away from a central axis (2) within a body lumen, such as an artery.  The stent (10) is formed form a series of struts (20) circumscribing a cylindrical contour of the stent (10). Each strut (20) has a series of bends (30) formed therein with each bend including at least one trough (32) and at least one crest (36). Gaps (40) are provided between adjacent struts (20). Each gap (40) is spanned by an axial element such as a tie bar (50) or links (180). Each tie bar (50) attaches to adjacent struts (20) through troughs (32) so that when the stent (10) is radially expanded, the struts (20) are not drawn together, but rather maintain their position and the stent (10) hence maintains its axial length without contracting. Other elements such as the links (180) can be provided spanning the gaps (140) to provide enhanced flexibility for the surgical stent (110) including such links (180).

Patent CA-2295065-A1 (CA)
Title: Packet-switch system
Inventor: MCKEOWN NICHOLAS W
IPC: H04L12/56
Filed: 1999-04-29
Abstract: A packet-switch system utilizes a linecard-to-switch (LCS) protocol to integrate linecards with a switch core. Since the linecards include a majority of the buffering of the system and are located physically away from switch core, the size of the switch core can be reduced in size. The LCS protocol is a label-swapping, credit-based, flow-control, which enables the system to operate without requiring such information as the number of port modules available within a switch core or what Qualities of Service (QoS) or multicast flows are available. In addition, the LCS protocol enables the linecards to contain and manage the majority of the buffers in the system, and also to control the data drop policy within the system.

IPC: H04N19/00
Filed: 2000-03-09
Abstract: An image data compressing device includes: a maximal value extracting unit and a minimal value extracting unit that respectively extract a maximal value anal a minimal value from pixel values in a prescribed region of image data; a level decision unit that determines quantization levels of the pixel values in the prescribed region based on the maximal and minimal values extracted; and a comparison unit that compares the images data with the quantization levels and outputs quantized data.

Patent CA-2305070-A1 (CA)
Inventor: LANGLOIS PIERRE
IPC: G11B7/1381
Filed: 2000-04-13
Abstract: A device and method for recording holographic gratings by the use of a single illuminating beam, two diffraction gratings, light detectors and a slit-scanning system. The beam illuminates two slits that then define two beams that are incident on the gratings. One diffracted order from one beam and one diffracted order from the other beam then interfere on a recording plane to produce sinusoidal variations of intensity. The interfering region may instantaneously be limited by a third slit. Also, another order of diffraction from one beam may be directed toward its own light detector and so is another order of diffraction from the other beam. These two detectors allow real time monitoring of the light intensity of each beam. By moving the slits in a direction parallel to the recording plane, an area larger than the slits' width can be exposed by the interfering pattern.

In one aspect the Tunable Vibration Absorber (TVA) (35) is adaptive in that the position of the mass is adaptively moveable with respect to its initial position, thereby effectuating a change in the TVA's resonant frequency. In one embodiment, the tuned mass (43) moves along a rigid frame (53). In another, movement of the mass (43) statistically stresses a preferably disc-shaped flexible plate (58) thereby changing its stiffness. Preferably, a reducer (78) gears down the speed of the motor (64). In another aspect, a TVA system includes a base sensor (40) providing a base vibration signal, a mass sensor (38) for providing a vibration signal of the tuned mass (43), and an electronic controller (42) for generating a control signal to the TVA (35).

The method and apparatus include positioning a coating composition dispenser (36) above a surface of a substrate with the coating composition dispenser (36) oriented to dispense a coating composition spray (40) generally normal to the surface of the substrate (31). A gas dispenser (38) is also positioned above the surface of the substrate (31) and adjacent the coating composition dispenser (36) with the gas dispenser (38) oriented to dispense a gas stream (46) generally normal to the surface of the substrate. The coating composition spray (40) and the gas stream (46) are spaced from each other so as to develop an interference effect therebetween adjacent the surface of the substrate. Preferably the substrate is maintained at a temperature which pyrolyzes the coating composition. The interference effect directs the coating composition to deposit over the substrate as a coating having a fade zone. In an alternative embodiment of the present invention, a plurality of coating composition dispensers and gas dispensers may be positioned over the substrate to provide one or more coatings on the substrate, each of which possesses at least one fade zone.

Une zone d'activation est un système de fichiers à lecture seule servant de base à des opérations d'établissement d'une configuration de choix. Différents utilisateurs de zones de travail peuvent intégrer leur travail par soumission du contenu de leur zone de travail à la zone d'activation. Dans cette dernière, des créateurs peuvent comparer leur travail et voir comment leurs modifications s'adaptent les unes aux autres. Une zone d'édition est un système de fichiers à lecture seule et le contenu d'une zone d'activation est copié virtuellement dans une zone d'édition, de manière à créer un instantané gelé à lecture seule du contenu de la zone d'activation. Une des mises en application de ce système et de ce procédé de gestions de fichiers consiste en un outil de création d'un site Web.
